As we all know, the earth is our home , but nowadays, the environmental problems are becoming more and more serious , which threaten our life., such as the air pollution ,water pollution and the noise pollution As far as I’m concerned, a good environment can make us feel happy and keep healthy, so we should try our best to protect our home . There are some things we can do, for example, we shouldn’t throw rubbish everywhere ,and some thing can be recycled, such as plastic bags, glass bottles and plastic bottles. At the same time , we also can plant trees and flowers to make our earth more beautiful .what’s more, as citizens ,we’d better not drive cars ,we can go to work or school by bus or by bike, and so on. All in all , we call on all the people who want to live in the earth happily : There is only one earth, please protect our home. 本文来源：https://www.wddqw.com/doc/07e7ad80366baf1ffc4ffe4733687e21af45ffb5.html
